WARREN, Maine — A 56-year-old Warren man has been charged with cruelty to animals.

Foster Sullivan was issued a summons, according to Knox County Sheriff Donna Dennison. He is scheduled to appear in Rockland District Court on May 21.

Two mixed breed dogs, 14 assorted breed chickens and six ducks were removed from the premises by the Knox County Humane Society, the sheriff said Monday. The animals have been placed in foster care.

One of the dogs may have to be put down, the sheriff said, because of the extent of the neglect.

The investigation began when Deputy John Hansen received a complaint of animal neglect. The sheriff praised the deputy’s work. The animals had inadequate food and water and were suffering from severe neglect, she said. The water in the pen for the dogs was green and unfit to consume, she said.

Sullivan also signed a transfer and release form to surrender the animals, the sheriff said.
